Specification of Letters Patent.

Application filed May 29, 1909.

Serial No. 499,089.

To all whom it may concern:

Be it known that I, Finn) E. YOUNGS, residing at Detroit, in the county of IVayne and State of Michigan, a citizen of the United States, have invented or discovered certain new and useful Improvements in Gas- Controllers, of which improvements the following is a specification.

It is customary to provide means to supplement the protection afforded by the regulater to prevent excessive pressure of gas in house service lines. The regulator is constructed and adjusted to maintain while operative a predetermined safe pressure in the service lines, but provision should be made to prevent excessive pressure in service lines in case the regulator fails to operate.

The invention described herein has for its object the provision of an outlet from the chamber of the regulator connected to the supply and service pipes, such outlet being normally closed by a liquid seal.

The invention is hereinafter more fully described and claimed.

In the accompanying drawing forming a part of this specification is shown in sectional elevation a regi'llator embodying my improvements.

The body portion 1 of the regulator is formed with a regulating chamber A, an inlet chamber B and a relief chamber C, so arranged with reference to the regulating chamber as to permit of a controlled connection between said chambers In the construction shown, a passage 2, which may be an extension or enlargement of the regulating chamber extends under the relief chamber. In that portion of the passage or extension 2, a cup 3 is arranged said cup being made preferably in the form of a hollow metal plug externally threaded so as to be removably secured in the under wall of the passage or extension. A tube 4 extends from the relief chamber down into mercury contained in the cup 3, the depth of immersion being dependent upon the maximum pressure to be maintained in the regulating chamber A. When the pressure in this chamber exceeds a predetermined maximum, the mercury will be forced from the cup into the tube, uncovering the lower end of the tube. IVhereupon there will be a sudden rush of gas up through the mercury into the relief chamber, which has a free outlet port 5, preferably connected by a pipe to the atmosphere. In this sudden rush of gas through the mercury contained in the tube a considerable quantity of mercury may be carried up into the relief chamber and some will be carried out of the latter unless provision is made to prevent such loss. To that end a battle-plate 6 is ar ranged above and in line with the tube 4 where it opens into the relief chamber. This battle-plate (3 is preferably hollowed or recessed as is indicated in the drawing, to the end that the mercury which may be thrown up against it by the gas rushing into the relief chamber may the more certainly be battled or thrown back to the bottom of the chamber. And the bottom of this relief chamber is, as the drawing indicates, preferably hollowed or sloped downward to the point where the tube lopens into it, that the mercury which has been battled back by the battle C shall be carried directly back through the tube 4 into the cup 3.

The entering the relief chamber passes through a passage 7 above and behind the battle plate to the escape orifice 5, and. in addition there is another recess or battle surface 11 in the upper wall of this relief chamher, and this batlie surface 11 also is hollowed as the drawing shows. The passage 7 lies between the two baffle surfaces 6 and 11. The purpose of the baffle surface 11 is supplement-a] and it will readily be understood. If there is no such surface, the stream of flowing out through the passage 7 might readily carry with it the Inercury which had been thrown up against the battle 6 and then thrown back into the stream, but with the supplemental baflle 11 any mercury which may thus be thrown back from the battle 6 and carried up along the bottom of the chamber by the flowing stream is caught in the baflle 11, and there relieved of the impulse of the flowing stream, and is thrown down again on the bottom of the relief chamber. However, the having lost a great part of its Velocity by expansion in the relief chamber, will flow laterally into and along the passage and the pipe connected to the outlet port 5.

The controlling or regulating mechanism in the chamber A maybe of any suitable construction, but preferably such as is described and claimed in an application Ser. No. 479,123, filed February 20, 1909. The diaphragm 8 is held in place by the cover 9 in the usual or any suitable manner and the chamber between the diaphragm and cover is connected by a port 10 to the relief chamber as shown.

I claim herein as my invention:

1. A regulator case or shell provided internally with a regulating chamber and a relief chamber, the regulator chamber extending beneath the relief chamber and separated therefrom by a transversely extending partition, in combination with a mercury cup arranged in the regulating chamber, and a tube extending from the relief chamber through said partition and into said cup, substantially as described.

2. A regulator case or shell provided internally with a regulating chamber, a relief chamber, and a diaphragm chamber, com- FRED ELLIOTT YOUNGS.
